6 Claims. (01. 38-66) The present invention relates to pull irons for of a frame comprising bars i1 and I3 connected ironing machines of the type having cooperating by a cross-member I! which has spaced ears 20 pressing members which are brought into enprojecting from the upper side thereof through gagement to iron material placed therebetween. openings of the shoe cover H. The bars l1 and 5 In ironing machines of this type there are cerl8 are secured to the upper side of the shoe by 5 tain types of irregular material, such as ruffles means of screws 2|, 22, 23 and 24. The bars i1 and the like, which are not conveniently ironed and I3 have clearance openings 25 around the by placing betwen the pressing members. Matescrews 22, 23, and 24'so that the frame can have rial of this type is more readily ironed by drawa limited pivotal movement about the screw 2|.

The complete circuit improved construction and arrangement in a pull to the pressure developing mechanism is not iron which is carried within the edges of one of shown. It includes a conductor 26 connected to II the pressing members when not in use and which the stationary contact 21 of a switch 28 fixed to is extended to a position projecting beyond the the upper side of the shoe and a conductor 29 pressing member when in use. connected to a flexible conducting strip 30 carry- In the accompanying drawing, Fig. 1 is an end ing the movable contact 3| of the switch.

The upper suris slidably carried on the upper surface oi. the face of the shoe is enclosed by a sheet metal cover shoe beneath the shoe cover l4. The pufl' iron M which fits against the outer edge of a rib I5 is made from a bar of metal and has a working 50 extending around the edge of the shoe. On the surface 42' at the front end which is spaced from front edge of the shoe are fixed wire guards it the upper surface of the shoe and has a part 43 which prevent the operator from being burned at the rear of the working surface which is slidby accidental contact with the shoe. able in a groove 44 in the upper surface of the The handle I is supported on the shoe by means shoe. The working surface 42' of the puff iron has rounded corners which provide a smooth surface across wihch the material to be ironed may be drawn. The puff iron is moved between the extended andretracted positions by a resilient wire lever 45 which has a hooked end 46 extending through an opening 41 in the bar ll and providing a pivotal support for the lever. The lever extends from the bar I8 transversely across the part of the puff iron remaining within the shoe and through an opening 48 in a boss 4! on the puil iron and out through a cam slot 50 in shoe cover l4, terminating in a handle ii. in Figure 4, the slot 50 is provided with downwardly inclined portions 52 and 53 respectively at the front and rear ends. When the lever rests in one of these inclined. portions the outer end of the lever is pressed downward below the level of the opening 48 in the boss 49 and the rear portion of the puff iron is accordingly pressed into intimate contact of the upper surface of the shoe.

The manner in which this pressure is obtained is illustrated diagrammatically in Figure 5, the

lever being shown at the front of the inclined portion 52 of the slot 50. This corresponds to the extended position of the puff iron in which the working surface 42' projects beyond the front edge of the shoe in a readily accessible position. The inclined portion 53 of the slot 50 is provided with a detent notch 54 which holds the lever in the retracted position. As the lever is moved from the retracted position, shown in full lines in Figure 2, to the extended position, shown in dotted lines, the handle 5| swings further away from the end of the shoe. The operator, therefore, has less chance of being burned while moving the put! iron.

When the puff iron is in the extended position, it is desirable that operation of the pressure developing mechanism be prevented. This is ac-' complished by the pivotingof the lever on the head of the screw 24 which serves as a fulcrum. When the lever 45 is in the dotted line position of Fig. 2, the bar I8 is moved to a position in which the tongue 33 separates the contacts 21 and 3| opening the circuit to the pressure developing mechanism and preventing operation thereof.

What I claim as new and desire to secure by Letters Patent of the United States, is:

1. In an ironer having a shoe, a puff iron carried within the edges of the shoe and having a working surface movable to a position projecting beyond an edge of said shoe when in use and having a part to the rear of said working surface remaining within the edges of the shoe, a lever having a handle projecting beyond the shoe and having a portion within the shoe extending transversely across said part of the puff iron remaining within the shoe, means mounting the lever,

on the shoe for swinging movement over the shoe in the direction of movement of said pufi iron, and interengaging portions on said lever and said part of the puff iron whereby the pull iron is moved between the extended and retracted positions by the swinging movement of the lever.

As shown 2. In an ironer having a shoe, a pull iron carried within the edges of the shoe and having a workingsurface movable to a position projecting beyond an edge of said shoe when in use and having a part to the rear of said working surface remaining within the edges of the shoe, a lever'for moving the puff iron on the shoe, and means carried by the shoe and engaging the lever for pressing the lever against the part of the puff iron to the rear of the working surface whereby said part of the puff iron is pressed against the shoe.

3. In an ironer, a shoe, a cover for the upper surface of the shoe, a puff iron slidably carried on the upper surface of the shoe beneath the cover and movable between a-retracted position within the edges of the shoe and an extended position having a working surface projecting beyond an edge of the shoe, a lever for moving the puff iron between the extended and retracted positions projecting through a cam slot in the shoe cover, and a connection between the lever and the puflf iron whereby the pull iron is pressed against the upper surface of the shoe by the action of the cam slot on the lever.

4. In an ironer having a shoe, a puff iron carried within the edges of the shoe and having a working surface movable to a position projecting beyond an edge of said shoe when in use and having a part to the rear of said working surface remaining within the edges of the shoe, a lever mounted on the shoe for movement over the shoe for moving the puff iron between the extended and retracted positions, means carried by the shoe and engaging the lever for exerting force on the lever for effecting pressing of the part of the puff iron to the rear of the working surface against the shoe.

5. In an ironer having a shoe, a puff iron carried within the edges of the shoe and having a working surface movable to a position projecting beyond an edge of said shoe when in use and having a part to the rear of said working surface remaining within the edges of the shoe, a lever mounted on the shoe for movement over the shoe for moving the puff iron between the extended and retracted positions, and cam means engageable by the lever during its movement for effect a ing pressing of the part of the puff iron to the rear of the working surface against the shoe.

6. In an ironer having a shoe, a puff iron carried within the edges of the shoe and having a working surface movable to a position projecting beyond an edge of said shoe when in use and having a part to the rear of said working surface remaining within the edges of the shoe, a lever mounted on the shoe for movement over the shoe for moving the puff iron between the extended and retracted positions, and carried in the shoe for pressing the lever against the puff iron whereby the part of the putt iron to the rear of the working surface is pressed against the shoe.
